TOS9200/9201 Basic Operations 3-9
Turning the offset cancel function ON/OFF
The offset cancel function can be turned on/off. When it is on, this function displays
the difference calculated by subtracting from the measured value the offset value
recorded by the function ("3.9 Offset Cancel Function").
• To use the recorded offset value, make the same settings for the frequency, LOW/
GUARD of the GND, and the scanner as were made for the offset value.
Each time the test voltage is changed, the recorded offset value is converted to
re fl ect the change.
For details, see "3.9 Offset Cancel Function".
The offset cancel function can be set to ON/OFF using the SHIFT + F3 keys,
regardless of the location of the cursor. Each time the SHIFT + F3 keys are pressed,
ON and OFF alternate.
The keys can also be used to move the cursor to ON/OFF of the offset
cancel function. If the cursor is at ON/OFF of the offset cancel function, the rotary
knob can be used to make settings.
Turn the rotary knob clockwise : ON
Turn the rotary knob counterclockwise : OFF
Turning the timer ON/OFF
Make ON/OFF settings for the timer function.
When the timer function is turned on, the test time can be controlled as shown in
“Setting the test time” in the next section. When the preset test time has elapsed
with a recorded leakage current between the lower and upper currents, the test ends
